THRESHING AND SEPARATING DEVICE OF A COMBINE HARVESTER Russian patent published in 2022 - IPC A01F12/00 

FIELD: agricultural engineering.

SUBSTANCE: claimed invention relates to agricultural engineering, in particular, to threshing and separating devices of combine harvesters. The threshing and separating device contains a frame 1, a threshing drum 2, concaves 3 installed under the working bodies, and a beater distributor 4. At the same time, two rotors 5 are introduced, pivotally mounted in the frame 1 on one side on a roller bearing, and on the other side on the gearbox shaft 7, and consisting of a welded cylindrical housing, two types of coils 9, 10 mounted in the front of the housing, slats 13 mounted behind the coils in the front of the housing, blades 21 mounted in the rear of the housing, brackets located on the outer surface of the housing between the slats 13 and the blades 21, rasp plates 12 with rasps 11 mounted on the surface of the slats 13, plates mounted on the blades 21, and pads 17 mounted on the brackets 16. The rotors 5 are located transversely to the longitudinal axis of symmetry of the combine and rotate in opposite directions relative to each other.

EFFECT: threshing and separating device provides an increase in the productivity of the combine harvester, a reduction in crushing and injury of grain, as well as a reduction in the breaking of the stalks of the technological mass and an improvement in its transportation.
